Question 1204593
Isabella is buying tickets to a concert. Adult tickets (x) cost $45 each and children tickets (y) cost $37 each. Isabella spent a total of $521 and purchased 3 more children tickets than adult tickets. Which is a viable solution for the system of equations?


Adult tickets (x) cost $45 each and children tickets (y) cost $37 each. 

 3 more children tickets than adult tickets. 
y=x+3

 Isabella spent a total of $521

45x +37y= 521

y=x+3
y-x=3  ( multiply by 45)
45y-45x= 135
45x +37y= 521

Add the two equataions
we get 82y = 656

y=8
So x=5

x=5 (number of adult tickets) and 

y=8 (number of children tickets).
